RE: [MW:12925] dual pipe certificate

By Materials & Welding

There should be no problems – your material is in accordance with SA 333 Gr 6 (and other standards).

 

Often you will see the same if you order flanges in A105N or A350 LF2. It will be the same flange with a certificate covering both material standards.

 

It is also often we see on the same certificate compliance with certain DIN and EN standards. It is nice when material manufacturers can tailor pipes, flanges and fittings so they are in accordance with a number of standards.

 

regards

Materials can be dual certified or even triple, as long as it meets all the criteria for what it is being certified for. SA-333-6 must have a Charpy for -50F / -46C.

Dear experts,

 

As per our order vendor should supply seamless pipe to SA-333 Gr 6, but he supplied the pipe with dual material certificate of SA-106 Gr B/SA-333 Gr 6. please let us have your comment.

please note that our design code is ASME B31.3.

 

Regards,

Karandish

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
